Description
MF Electronics R-Series industrial tem-
perature range surface mount (SMD)
oscillators provide low jitter clock wave-
forms needed to clock standard HCMOS
or TTL circuits in PCBs mounted in
rugged environments.
FEATURES
• Industrial operating temperature range from -40º to +85ºC accommodates rugged environments
• Low jitter of 5 ps RMS max ensures stable data transmission
• Stability options of ±100 ppm to ±25 ppm
• 45/55 symmetry is standard
• Guaranteed start-up with ramping DC Supply
• Start up time less than 5 ms
CONNECTIONS
• Tristate option available
• Very low power when tristated
